Introduction

Delphi implementation of Int128 and UInt128 data type using operator overloading.

Valid range for Int128: -170,141,183,460,469,231,731,687,303,715,884,105,728 to 170,141,183,460,469,231,731,687,303,715,884,105,727

Valid range for UInt128: 0 to 340,282,366,920,938,463,463,374,607,431,768,211,455

Example

uses int128impl;

var a: Int128;

begin
  a := High(UInt64);   // 18446744073709551615
  a := 2 * a;
  WriteLn(a.ToString); // 36893488147419103230
  Readln;
end.
